SEWER-CLEANING DEVICE.

Be it known that I, PATRICK J. HEALEY, a citizen of the United States,and a resident 'of Jersey City, in the county of Hudson and State ofNew' Jersey, have made and m-' vented certain new and usefulImprovements in Sewer-Cleanin Devices, of which the following is aspecification.

My invention relates to sewer cleaning devices designed to remove suchaccumulation of solid material as may have collected within asewer, orrather in a section thereof between two manholes, the invention havingparticular reference to that type or class of sewer cleaning devices inwhich a'bucket is drawn through the sewer by means of a suitable ropeand during which it scoops up a load of the material to; be removed,after which the same is elevated to" the surface of the ground through asuitable manhole; an example of which class of devices is shown in myPatent No. 775,677, for machine for cleaning sewers, patented November22, 1904:, and of which device the sewer cleaning mechanism to whichthis present application relates is an improvement.

Theobject of the invention disclosed and claimed herein is to provide asewer cleaningmechanism or device of the class'above referred to whichmay be operated entirely from one end of the sewer or section thereof tobe cleaned. v A further object of my invention is to provide improvedmeans for accomplishing the dumping of the contents of the bucketemployed after it has been elevated to the surface of the ground; andfurther objects of my invention will appear in the following"description, wherein-the particular features thereof are pointed o-utatlength.

With the above and other objects in'view, my invention consists in theimprov'dsewer cleaning device illustrated in the accompanying drawings,described in the following specification, and particularly claimed, andin such variations and modifications thereof as will be obvious to thoseskilled in the art to which my invention relates.

In the drawings accompanyingand form- .ing a part ofthis specification,and wherein the preferred embodiment of my invention is illustrated Fgure 1 is a view showing my improved sewer cleaning device installed ina section of sewerto be cleaned; and

Specification of Letters Patent.

Patented Aug. 19, 1919.

Application filed February 1', 1919. Serial No. 274,427;

2 is a view upon a larger scale illustrating my invention and in whichcertain "portions thereof are shown in two positions,

in order that the operation thereof may be better explained.

- Referrlng now to the drawings, the reference numeral 5 designatesasection of sewer to be cleaned, and 6 and 7 are two manholes leadingfrom the surface of the ground into the sewer and through which entrancemay be had thereinto, these being the usual manholes present n sewersystems in common use.

" Located adjacent the manhole 6 iswinding Y -mechanism of any suitableform, so far as my invention regardedin its broader aspects isconcerned,which mechanism, however, is shown as 1n the form of two wlndin drums 8,9, both of which are'o perated rom an gine, so that either drum may beoperated independently of the other. I

' The reference numeral ll'designates the bucket of my'improved sewercleaning'device which is 'drawn back and forth through the section ofthe sewer to be cleaned, the same being provided with wheels 12 in orderto reduce the friction, as willbe appreciated. The main body portion ofthe bucket maybe of various forms, the form illustrated in the..drawings being cylindrical in cross section. The lower end ofthe bodyof the bucket is closed by two doors l3 pivotally connected to the lowerend of the side wall thereof, and with which doors the ends of two fiexible members such as chains 14 are connected, as best shown in Fig. 2.These flexible members extend through guides 15 secured to the innersurface of thelwall of the bucket and are connected at their upper endwith a ring 16 ;jwith whichring the end of a lifting rope isconnectedto' thereby move the bucket to the left, Figifl, and then lift itthrough the manhole6 and dump its contents .into a tank,,wagon, or otherreceptacle, as indlcated in 2. I

llhe bucket 11 is filled by moving the same to theright, Fig. 1, whilethelower the bucket is moved the end. of the door which slides along thebottom of the sewer will scoop up material to be removed and cause theentrance thereof into the body of the bucket.

The engine and winding "or hoisting mechanism is commonly supportedupon'any -=suitable base such as is indicatedbythe ref erence numeral 17and 18 designates a boom boom supports a pulleyorsheave block 20 havingtwo wheels or sheaves to accommodate two. ropes 1n the embodiment of myinvention illustrated; and the position ,of

said boom is controlled by a rope 21, one end of which is connectedat:22 with .a-cross bar 23 of a vertically; arranged framework 24carried by the base 17, and which rope passes about a pulley 25. carriedby the" boom, and thence over the cross bar 23 and to thelefthand end ofthe framework, where it is secured to any suitable fastening device suchas is indicated by the reference nume al 26. The purpose :of this-ropeis to :permit the boomto swing-into the position showninfull linesinFig. 2 when the bucket Y vis to be dumped, and to return the same intothe position shown in dotted lines in Fig. 2, and in Fig. 1, when thebucket is to be lowered into or drawn up through the manhole 6 l't willbe appreciatedthat this swinging movement of, theboom maybe accomplished by any rope or equivalent, member whereby the boom maybeoperated to at- ;tain the result above referred to;

, The reference numeral 27' designates a fixed abutment secured, inplace at the end of thesection ofsewer to be cleaned which is l remotefromthe winding mechanism and other elements of the device, and whichabutment serves as a fixed support for a ,pulley 28; and a second fixedabutment 29 is secured in place within the sewer at the end thereofadjacent the hoisting drums, and

The. reference numeral 32 designates a guide pulley rope whichextendsfronrthe surface of the ground where its end is secured to. any supportdownward through the manhole 6 and about the pulley 31 and the free endofwhich-rope is connected with a guide pulley 3.3; the purpose of saidguide pulley being to change the direction of the rope,- whereby thebucket 11 is moved to the 7 left from the horizontal to the vertical,and

to permit the bucket to be lifted through the manhole, during whichmovement the guide pulley moves upward-along with the bucketythe end o ftherrop'ewwhich is secured to a fixed support at the surface of theground being unfastened at the beginning of the upward movement of thebucket and as the same is tipped from the horizontal position in whichit is shown in Fig. 1 into a vertical position preparatory to hoistingit through the manhole 6, as will be appreciat'ed.

,The movement of the bucket to the right is produced by a rope 3aoperated by the tothe remote endiof the section of sewer to be cleanedand about the pulley 28, and

thence to thebucket the end of said rope being connected either directlywith the body of the bucket or with the lower of the .swingingdoorsthereof, the latter being the method o f connection illustrated in thedrawings, It will be understood from the above thatupon rotary motionbeing 1mpart ed to the said drum 8 the bucket will be moved to -theright, during which the.

solid matter will be scooped up. and carried into the body of thebucket, thus filling the same.

After the bucket llhas been filled by a movement to the right it isdrawn to the .left by means ofa lifting rope 35 operated by the, winding:drum 9 'and which rope passesv upward and about the other of thesheaves of the pulley 20, thence downward through-the manhole 6 andthrough the guide pulley 83 thence along the section ;of sewer tobecleaned to the bucket; where it .iseconnected with the ring 16 at theends of the flexible members l-i, the other ends ofwhich flexible memberareconnected with thedoors 13 as hereinbefore explained. The firstmovement of the said rope to the'left will obviously close the doors 13,thus retaining. whatever material may have been scooped up by thebucket, and the load which the bucket contains is obviously supportedbythe said flexible members operating through the doors while thebucketis being V I ,moved along and lifted through the manhole wh chlast. mentloned abutment serves as a I support for two pulleys 30,311.,

6, and until the same is discharged from the bucket 1n the mannerhereinafter explained.

I Vvheir the bucket reaches about the posi- *t1on indicated by dottedlines in Fig. 1, the free end of the guide pulley rope 32 atthe:

surface of the ground is released, whereupon and asthe bucket is liftedthrough the manhole 6 the'guidepulley passes along with the 'bucket, asindicated'in' Fig. 2. It will of course be understood that the guidepulley several -trips of the bucket through the section of sewer to becleaned are ordinarily necessary in order to remove all the sediment orsolid material therefrom. 1

The dumping of the contents of the bucket 11 after it has been movedinto the position shown in Fig. 2, is accomplished by a dumping rope 36having a hook 37 at its free end, and which rope extends through orabout guiding means located adjacent the end of the boom, as through a100p or eye 38' carried by the pulley block 20, and the other end ofwhich is adapted to be secured to a fixed support indicated by thereference numeral 39, and which dumping rope serves to support the bodyof the bucket and permit the lifting rope to be slackened; whereupon thedoors will open and the contents thereof escape through the bottom ofthe bucket.

In order to accomplishthis operation two chains 40 are provided, thelower ends of which are secured to the body of the bucket in any way, asby eyes carried by the guides 15 hereinbefore referred to. The upperends of these chains are preferably connected with a ring 41 with whicha hook 42 is connected through a short piece of chain, in order toprovide for the convenient attachment or engagement of, the hook 37 ofthe dumping rope with the bucket in sucha manner that the same may besupported by the dumping rope after it "has been elevatedandswungintothe dumping position shown in: Fig. 2, whereupon and as the liftingrope 35 is slackened the doors 13 will, open and per mit the contents ofthe bucket to escape.

The hook 42 should be-hooked into the ring 16 when the bucket is to belowered through the manhole 6, in which condition it re mains during thefilling operation thereof,

and during the subsequent movement of the bucket to the left and whileit is being lifted through said manhole, in order that the said hook maybe in an easily accessible position when the hook 37 of the dumping ropeis to be engaged therewith.

It will be appreciated, that the dumping rope is connected with thebucket when the same reaches about the position in which it is shown indotted lines in'Fig. 2 upon its upward journey, and that said dumpingrope is disconnected from the bucket before the'same passesback into thesewer. The said-rope is of course kept taut while the bucket is passingfrom the dotted line' position shown in Fig. 2 into the dumping posi:tion, and is then fastened to the securing member 39, or held inthehand, while the bucket isdumped. Thereafterand until the bucket reachesthe dotted line position in Fig. 2 upon' its return movement into thesewer the said'rope is slackened,and per mi-tted to move through theguide 38, and the said rope is unhooked from the bucket when the samereaches thedotted' line position referred to. 1 a
